Hello. You did not enter the text to which this question refers, which makes it impossible for me to provide a specific answer. However, I am going to show you the possible uses of ellipsis, so you can evaluate how the author used it in the text you have.
Ellipsis is commonly used to indicate interrupted thoughts and hesitations in the speech of a character or narrator. These are the most common uses, which you will find easily in various texts. An example can be seen in the sentence: "When I joined ... I don't know ... can I start again?"
Another common use of ellipsis is to suppress parts of a text that is being rewritten. This form is more common in nonfiction texts, which may present summaries of other texts.
